Fast Recognition of BCI-Inefficient Users Using Physiological Features from EEG Signals: A Screening Study of Stroke Patients
(Frontiers, 2018-02-21)Motor imagery (MI) based brain-computer interface (BCI) has been developed as an alternative therapy for stroke rehabilitation. However, experimental evidence demonstrates that a significant portion (10% to 50%) of subjects ... -
Fast Stress Detection via ECG
(University of Waterloo, 2019-05-23)Nowadays stress has become a regular part of life. Stress is difficult to measure because there has been no definition of stress that everyone accepts. Furthermore, if we do not get a handle on our stress and it becomes ... -
Fault Detection and Identification in Computer Networks: A soft Computing Approach
(University of Waterloo, 2010-01-07)Governmental and private institutions rely heavily on reliable computer networks for their everyday business transactions. The downtime of their infrastructure networks may result in millions of dollars in cost. Fault ... -

(University of Waterloo, 2005)Powered orthotic devices can be used to restore mobility to the impaired user, and may thereby assist them in daily living tasks. An investigation is performed herein to examine the feasibility of a powered lower-limb ... -
A Feasibility Study of Micromachined Ultrasonic Transducers Functionalized for Ethanol Dectection
(University of Waterloo, 2017-08-01)The chemical sensing system plays an important role in medical and environmental monitoring. Gases exhaled by humans include nitrogen, oxygen, water vapor, carbon dioxide and volatile organic compounds (VOCs). The VOCs are ... -
Feature Analysis and Classification of Inflammatory Bowel Disease and Hidradenitis Suppurativa Using Data Mining
(University of Waterloo, 2023-03-14)Inflammatory Bowel Disease (IBD) refers to a group of conditions that primarily affect the gut and cause inflammation. In contrast, Hidradenitis Suppurativa (HS) is a chronic immune-mediated condition characterized by boils ... -
Felines, Foragers, and Physicists: Supporting Scientific Outreach with Multi-Surface and Multi-Space Games
(Association for Computing Machinery, 2016-11-06)We describe the design, development, and deployment of two scientific outreach games to support an open house event at an Institute for Quantum Computing (IQC) by an 11-member team of academics and practitioners over a ... -
Financial Fraud Detection and Data Mining of Imbalanced Databases using State Space Machine Learning
(University of Waterloo, 2016-01-04)Risky decisions made by humans exhibit characteristics common to each decision. The related systems experience repeated abuse by risky humans and their actions collude to form a systemic behavioural set. Financial fraud ... -
Financial Literacy through Gameful Design
(University of Waterloo, 2021-01-29)Canadians have been found to have little to no expendable income and find debt management difficult. Alongside the growing push towards digital service platforms replacing traditional brick and mortar solutions within the ... -
A flexible, scalable, and self-powered mid-infrared detector based on transparent PEDOT: PSS/graphene composite
(Elsevier, 2020-01)A flexible, self-powered and semi-transparent mid-infrared photodetector is demonstrated with graphene and poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT: PSS) composite on poly vinyl alcohol (PVA) ... -
A Foot Placement Strategy for Robust Bipedal Gait Control
(University of Waterloo, 2008-05-23)This thesis introduces a new measure of balance for bipedal robotics called the foot placement estimator (FPE). To develop this measure, stability first is defined for a simple biped. A proof of the stability of a simple ... -
Foot–ground contact modeling within human gait simulations: from Kelvin–Voigt to hyper-volumetric models
(Springer, 2015-12)This study describes the development of a multibody foot–ground contact model consisting of spherical volumetric models for the surfaces of the foot. The developed model is two-dimensional and consists of two segments, the ... -
Formulation of a Path-Following Joint for Multibody System Dynamics
(University of Waterloo, 2015-03-23)The development and validation of a new multibody joint that constrains a body to follow a spatial path and an orientation defined by a user is presented. The resulting joint has a single degree of freedom (DOF), and ... -
Forward Dynamic Simulation of a Golf Drive: Optimization of Golfer Biomechanics and Equipment
(University of Waterloo, 2018-01-18)Advances in golf club performance are typically based on the notion that golfer biomechanics do not change when modifications to the golf club are made. A full-swing forward dynamic golf drive model, including impact and ... -
